Which of the following complex will give a white precipitate with BaCl2 (aq)?
Correct answer: C. [Cr(NH3)5Cl]SO4
- A. [Cr(NH3)5SO4]Cl
- B. [Co(NH2)4SO4]NO2
- C. [Cr(NH3)5Cl]SO4
- D. Both (A) and (C)
Explanation
BaCl2 gives white precipitate of BaSO4 with SO4 ions, so the complex must have SO4 ions in the ionization sphere.
